hydrodynamic performance analysis of modular chain-type floating docks for high-speed boat operations in semi-enclosed port basins: a multi-body simulation approach using ansys aqwa

This study investigates the hydrodynamic performance of modular, chain-type floating docks designed for high-speed boat deployment within the operational zone of shahid bahonar port. given the limitations of fixed dock infrastructure—particularly in regions with soft seabeds and tidal variations—floating docks offer a flexible, cost-effective alternative. a modular pontoon system was designed using catia and analyzed in ansys aqwa under various wave conditions (0°, 45°, 90°, 135°, and 180°). comparative simulations between single-body and multi-body configurations revealed that multi-hull docks significantly reduce vertical displacement and better distribute wave-induced forces, especially at connection points. time-domain analyses further confirmed that joint stiffness and orientation strongly influence structural response. elastic mooring systems enhanced the dock’s adaptability to dynamic sea conditions while minimizing environmental impact. these findings support the development of resilient floating marine structures tailored to the hydrodynamic conditions of semi-enclosed ports like shahid bahonar, with implications for both defense and commercial applications in high-salinity environments.
